74LS00

Abstract: 74LS00 TTL such chip is the 74LS138 3-to-8 decoder which is capable of handling four HCTL-1100s. Read , subroutine overhead. The HCTL-1100 bus interface circuit is capable of supporting four HCTL-1100s with no additional logic. If an I/O port based design requires more than one HCTL-1100, the interface The choice of which interface is most appropriate for your application should be based on whether or not your , glue logic. Bus Interface The I/O routines are slightly more complicated for the I/O interface than

3 to 8 line decoder using 8051

Abstract: 74LS00 circuit is capable of supporting four HCTL-1100s with no additional logic. If an I/ O port based design , chip could be used. One such chip is the 74LS138 3-to-8 decoder which is capable of handling four , -1100 and the second approach uses the 8051's I/O ports to communicate with the HCTL-1100. The choice of , port interface. The I/O interface requires no additional glue logic. The I/O routines are slightly , . These lines would control OE (Output Enable) and CS (Chip Select) for each of the individual HCTL
